a motorboat is headed at a velocity of 25 kilometers/hour toward the north, while the velocity of the water current is 12 kilome
1 answer:
The magnitude of the boat's resultant velocity will be 13 kilometers/hour.
<h3>What is velocity?</h3>The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is kilometers/hour.
The magnitude of the boat's resultant velocity is found as;
Hence, the magnitude of the boat's resultant velocity will be 13 kilometers/hour.

Answer:
Percentage increase in the fundamental frequency is
d)-14.02%
Explanation:
As we know that fundamental frequency of the wave in string is given as
now it is given that tension is increased by 30%
so here we will have
now new value of fundamental frequency is given as
now we have
so here percentage change in the fundamental frequency is given as
% change = 14.02%
1. B. T
The period of a simple pendulum is given by:
(1)
where
L is the length of the pendulum
g is the gravitational acceleration
From the formula, we notice that the period of the pendulum does not depend on the mass of the bob. Therefore, when the bob's mass is doubled, the period does not change.
2. C: sqrt(6)*T
In this case, the pendulum is brought to the moon, where the gravitational acceleration is
If we substitute this value into the equation for the period (1), we find the new period of the pendulum:
3. B: It will no longer oscillate because there is no gravity in space
Explanation:
The motion (oscillation) of the pendulum is caused by the force of gravity, which "pulls" the bob towards the equilibrium position. If there is no gravity, then there is no force acting on the bob, therefore the pendulum can no longer oscillate.
So, the correct answer is
B: It will no longer oscillate because there is no gravity in space
Here's a perfect example of a stable and unstable system.
